Abstract
This specification covers non-asbestos fiber-cement pipe intended for use in storm-water drainage of highways, airports, farms, foundations, and other similar drainage systems. The pipes shall be classified as Type I and Type II. Fiber-cement drain pipes shall be composed of an intimate mixture of an inorganic hydraulic binder or a calcium silicate binder formed by the chemical reaction of a siliceous material and a calcareous material reinforced by organic fibers, inorganic non-asbestos fibers, or both. Crushing strength test shall be performed to conform to the specified requirements.
Scope
1.1 This specification covers non-asbestos fiber-cement pipe intended for use in storm-water drainage of highways, airports, farms, foundations, and other similar drainage systems.
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
NOTE 1: Experience has shown that the successful performance of this product depends upon the proper selection of the pipe strength, the type of bedding and backfill, care that the installation conforms to the construction specifications, and provision for adequate inspection at the construction site. This specification does not include requirements for bedding, backfill, the relationship between field load conditions and the strength designation of the pipe, or durability. These requirements should be included in the project specification.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
